Repeated pustular pimples on the face may be caused by folliculitis and acne, and patients should consult a doctor in time to clarify the cause of the disease and then treat it. 1. Folliculitis: Bacterial infections such as Staphylococcus aureus can cause pustular pimples on the face, which can be triggered by factors such as high temperature, excessive sweating, scratching, and poor hygiene, resulting in recurring rashes. Patients will also have localized redness, swelling and pain. 2. Acne: If adolescent patients have recurrent pustular pimples on their face, it should be considered to be caused by acne, which is mainly caused by factors such as increased androgen levels, exuberant sebum secretion, propagation of Propionibacterium acnes, and immune-inflammatory response. It is necessary to go to the hospital for consultation, to clarify the cause of the disease, and to carry out treatment under the guidance of the doctor.
